Abstract

An acoustic identification and classification system of frogs has been designed based on the principle of wavelet extraction and label classification using an artificial neural network (ANN). This system consists of electronic detection for frog audio as well as an interface using the MATLAB 2018b software as an ANN provider device. As input for the neural network, 5 types of frogs were used, namely the rock frog (Limnonectes macrodon), the blentung frog (Kaloula baleata), the hip frog (Limnonectesblythii), the rice field frog (Fejervarya cancrivora), and the trench frog. frog. frog (Fejervarya limnocharis). ), each with 12 sound samples. Before being inserted into the neural network, 3 levels of sound samples were extracted and denoised using wavelet symlet 3. Furthermore, in the neural network training process, 3 validation samples and 3 test samples were used. After training, the artificial neural network was able to identify the type of frog being tested.

Abstract

Thalassemia is an autosomal recessive genetic disorder that remains a significant public health concern in Indonesia; consequently, early detection of carriers is crucial to prevent the birth of children with thalassemia major. This study aims to analyze the risk of thalassemia among Biology students at the Faculty of Mathematics and Natural Sciences (FMIPA), Universitas Riau, utilizing a simplified laboratory screening approach. The research involved 30 students who participated in genetic risk questionnaires, hemoglobin level assessments using digital hemometers, and erythrocyte counts via hemocytometers. The findings revealed a questionnaire risk score of 0.07 (categorized as very low), a mean hemoglobin level of 12.73 g/dL, and an erythrocyte count of 5.22 million cells/µL, both of which fall within normal physiological ranges. These results indicate that the risk of thalassemia among Biology students at FMIPA Universitas Riau is remarkably low. Simple screening through questionnaires, hemoglobin levels, and erythrocyte counts can serve as an effective method for both educational purposes and the preliminary screening of thalassemia carrier risk in students.
